- connection fitting of the type mentioned above, which is downstream of a branch fitting in the flow direction of the strand.
- branch fitting a partial flow of the strand is led out and passed over a loop to one or more consumers.
- the ring line opens into the threading of the connection fitting.
- a cross-sectional constriction acts in the manner of a nozzle and between the branch and the threading causes a pressure difference, through which a flow is generated in a flow in the strand in the ring line.
- each main line should be understood, regardless of whether this extends within a floor and within the floor several consecutively arranged wet cells via a respective ring line with Trinkg. Domestic hot water supplied, or as riser pipe, for example, in several floors superimposed wet cells interconnected.
- connection fitting of the aforementioned type is known as part of an ultrapure water supply system.
- the loop return flow from the loop into the strand is introduced into the connection fitting at an angle of about 90 degrees to the main flow direction.
- the main flow direction is that direction in which the main flow, ie the flow within the strand, runs.
- the connection fitting known from DE 39 19 074 has a cross-sectional constriction which acts in the manner of a Venturi nozzle and effects a pressure in the region of the threading opening which is lower than the pressure in the strand, so that in relation to one of the cross-sectional constriction upstream location of the valve , For example, at the inlet opening, a differential pressure loss occurs.
- connection fitting is known from US 5,622,203.
- the connection fitting forms part of a hot water circulation system and connects the hot water circulation line to a public drinking water supply network.
- the connection fitting ensures that hot water is immediately available at a tapping point connected to the system when hot water is withdrawn.
- the connection fitting acts in the manner of a venturi nozzle, which comprises a cross-sectional constriction located upstream in the flow direction of a threading opening of the circulation line realized by a gap and a cross-sectional widening downstream of the threading opening in the flow direction.
- the Venturi effect creates a lower pressure in the area of the threading opening (the gap), thus generating a suction which allows the water from the circulation pipe to flow back into the circulation pipe via the gap at an angle of approximately 90 ° circulating water with the drinking or service water from the public drinking water supply network is mixable.
- the present invention seeks to provide a connection fitting of the type mentioned, which leads to improved flow conditions in the region of the ring line associated with the connection fitting. Furthermore, with the present invention, a water pipe system with at least one floor or riser pipe, in which a plurality of ring lines are connected via Ausfädel- and Einfädelö réelleen, and one between the Ausfädel- and Einfädelö foundeden the associated loop in the strand provided cross-sectional constriction, which meets the practical requirements in an improved manner.

H. the effective pressure within the strand.
- any desired flow characteristic in particular any flow division, i. the distribution to partial flows through the loop on the one hand and by the strand on the other hand, can be achieved.
- the means for varying the average area of the cross-sectional constriction can be controlled by motor.
- the average narrowing can be effected for example by a movable throttle element, which is relative to a cross-sectional constriction provided in the strand in a fixed position between the inlet and outlet openings.
- this throttle element is in its initial position, which in the present case indicates that position at which the maximum possible cross-sectional constriction is achieved in the strand, held in the region of the cross-sectional constriction to form a leakage flow gap.
- This preferred embodiment ensures that even at relatively low volume flows in the strand a partial flow flows through the strand, so that at no time the total flow in the strand can be done solely by the ring lines and bypassing that length portion extending between the Ausfädel- and threading the respective ring lines, which would lead to the germination of these flow sections.
- the aforementioned low currents in the strand can be adjusted, for example, when the strand is opened even when not in use, for example by an end-side valve, to flush the respective strand and to empty stale optionally contaminated water.
- this effect can also be achieved by providing a bypass permitting the leakage flow in the region of the cross-sectional constriction.
- the throttle element sealingly abut the cross-sectional constriction, without the leakage flow is hindered. Accordingly, according to the embodiment of the present invention, only leakage means must be provided which allow the corresponding leakage flow through the strand, ie a leakage flow to the exclusion of the ring line.
- the leakage should be dimensioned so that up to a first lifting of the throttle element from the stationary relative to a connection housing provided flow constriction sufficient flow through both the loop and the continuous strand is effected.
- Each small flow within the strand should accordingly lead to a flow and thus flushing of both the loop and the strand.

H. the configuration, which is usually formed stationary relative to the housing of the connection fitting, is formed by a cone whose upstream surface is a nozzle, i. forms the narrowest cross-section in the strand, and the other conical surface is preferably formed as a diffuser and forms a contact surface for a conical mating surface, which is formed by the throttle element.
- the conical surface of the throttle element and the conical surface of the double cone need not have the same contour and / or inclination. Rather, both surfaces may have different contours and / or inclinations.
- the throttle element is preferably held by a spring element under bias, in such a way that the throttle element is present in the starting position against the cross-sectional constriction.
- the spring characteristic of the spring element can be adjusted with regard to the desired partial flows, depending on the pressure or flow conditions in the strand with changing total flow.
- the means further comprises a guide element which holds the throttle element movable.
- the guide element is preferably supported on the inner circumferential surface of the housing of the connection fitting, so that the throttle element is defined and held within the housing defined.
- an insert part which, in addition to the guide element, also forms a constriction section which precedes this in the flow direction and which forms the cross-sectional constriction.
- the means for varying the passage area of the cross-sectional constriction in the form of a unitary insert part can be built into the strand and realized. Accordingly, the means can be used for retrofitting in conventional, cylindrical branch lines, from which loop lines depart.
- the insert can be used in this case in a pipe section of the strand.
- the insert in an original equipment of a connection fitting, it is preferable to provide on the outer peripheral surface of the insert locking means which are provided there preferably spaced apart in the circumferential direction. With these locking means the insert is held within the valve body.
- the locking means are preferably formed by latching lugs which engage in formed on the inner peripheral surface of the valve body locking grooves.
- latching grooves are those recesses to understand that are provided spaced from each other in the circumferential direction and each cooperate with a single latching lug.
- such locking grooves can be realized continuously in the form of a circumferentially formed on the inner circumference of the valve body recess.
- the guide element extends into the region of the threading, ie partially covers the threading in the region of the connection fitting and forms a Ring effetsströmungs- passage, which passes through the guide portion, so that the loop flow through the guide element in through the main flow can be recycled in the strand.
- the development specified in claim 13 offers the possibility to perform within the connection fitting a so-called inliner, which is usually provided as a circulation pipe in a pipe-in-pipe circulation line and usually warm water leads to the consumer. Accordingly, the connection fitting according to this development is particularly suitable for a hot water circulation system.
- the inner tube is preferably used according to a further preferred embodiment, to guide the throttle element displaceable.
- a leakage flow is allowed, which also passes through the passage area of the cross-sectional constriction when the throttle element is in its initial position.
- the guide member at at least one of its end faces with a plurality of support ribs which define the outer peripheral surface and extend in the axial direction.
- Support webs adjacent in the circumferential direction form a gap through which the introduced loop flow can pass the guide element in the radial direction with respect to the longitudinal axis of the run.
- the corresponding support webs are preferably funnel-shaped, whereby the introduction of the inner tube is facilitated during assembly of the connection fitting.
- FIG. 1 is a perspective view of an insert part of the embodiment with the flow inlet in the initial position of the throttle element.
- Fig. 2 is a side perspective view of Figure 1 in the fully open position of the insert part.
- FIG. 3 shows a perspective side view of the insert part shown in FIG. 1 with the flow outlet;
- FIG. 4 shows a longitudinal sectional view through a part of a strand in the region of the connection fitting in the case of a throttle element in the starting position
- FIG. 5 shows the view shown in FIG. 4 with the throttle element fully open
- Fig. 7 is a graph showing a comparison of the flow characteristic in the ring line in dependence on the pressure difference between the threading and threading
- Figures 1 to 3 show an insert 2, which may be formed of metal or plastic and which is formed with a cylindrical outer peripheral surface substantially corresponding to a cylindrical inner peripheral surface of a valve body, which is shown in Figures 4 and 5 and identified there by reference numeral 4 ,
- the arrow S drawn in FIGS. 1 to 3 illustrates the flow direction of a main flow flowing through the strand, which is designated by reference symbol H in FIGS. 4 and 5.
- the flow through the loop is indicated by reference H.
- the insert part 2 At its front end in the flow direction, the insert part 2 has a plurality of circumferentially distributed webs 6, which continue the cylindrical outer peripheral surface and are funnel-shaped inwardly directed at its free end. A corresponding embodiment also has the end remote from the flow. There, the webs are marked with reference numeral 8. This area of the insert part 2 forms a guide element 10 for a throttle element 12. Between the front webs 6 and the rear webs 8, the insert part 2 a ring portion 14, the inner peripheral surface of which forms a conical surface 16 which cooperates with a conical surface 18 of the throttle element 12.
- a nozzle cross section formed by the ring section, which forms a cross-sectional constriction V with respect to the main flow H, is projected radially inwardly from the webs 6.
- the nozzle has at its narrowest point a larger diameter than the inwardly drawn webs 6, which form a stop for the throttle element 1.
- a plurality of latching lugs 20 are formed on the outer peripheral surface, which engage in latching grooves 22 which are recessed on the inner circumferential surface of the valve housing 4.
- a ring 24 is provided, which comprises the throttle element 12 and circumferentially leads, and forms a support surface 26 for a spring element 28, which extends between this ring 24 and an annular surface 30 of the throttle element 12 extends, which adjoins in the flow direction immediately behind the conical surface 18 of the throttle element 12.
- the tapered inwardly tapered free ends of the webs 6, 8 form in the embodiment shown a funnel-shaped opening, which facilitates the penetration of an inner tube 32 shown in Figures 4 and 5 of an inliner.
- This funnel-shaped opening has a diameter approximately corresponding to the outer diameter of the inner tube 32.
- the inner diameter of the nozzle at its narrowest point is about 15 to 25% larger than the diameter of the funnel-shaped opening.
- the inner tube 32 passes through a central bore of the throttle element 12. This is presently guided by the inner peripheral surface of the ring 24 and in the flow direction S adjoining webs. Selected webs can engage in axial grooves, which can be formed on the outer peripheral surface of the throttle element 12, whereby an anti-rotation of the throttle element 12 is formed.
- the insert part 2 with its guide element 10 is located in the region of a threading opening 34 of a ring line not shown in detail, which upstream of the insert part 2 with a Ausfädelö réelle of the strand goes off, leads to one or more consumers, such as a wet room in a hotel, and is returned to the strand in the area of the connection fitting.
- the circumferentially spaced rear lands 8 thus form a looped flow passage 38 through which the loop flow can flow radially inwardly to unite with the main flow H.
- the throttle element 14 With increasing pressure difference across the cross-sectional constriction, the throttle element 14 is urged against the force of the spring element 28 in the flow direction to the rear. As a result, the cross-sectional constriction V is increased until the throttle element abuts against the front end of the guide formed by the guide 10. This is in the present case formed by hook-shaped radial projections 40 of the rear webs 8.
- the resulting flow characteristic in the ring line is illustrated in FIG. 7 in comparison to a conventional flow characteristic K of a constant throttle.
- K a conventional flow characteristic
- L a leakage flow
- pressure changes in this area results in a flow characteristic corresponding to a conventional throttle, but by a constant flow cross-section, which is formed by the leakage flow.
